[0029] Example 1

[0030] As mentioned in the background section, in order to solve the problems existing in the prior art, this embodiment provides a car seat ventilation system with a universal ventilation bag, including:

[0031] Seat foam 1, with multiple first ventilation holes 11 provided on the seat foam 1;

[0032] Ventilation bag 2, the ventilation bag 2 is located on the side of seat foam 1 away from the human body, and multiple second ventilation holes 21 are opened on the side of ventilation bag 2 close to seat foam 1;

[0033] An air guide structure is located between the seat foam 1 and the ventilation bag 2. One end of the air guide structure is connected to multiple first ventilation holes 11, and the other end is connected to multiple second ventilation holes 21.

[0034] Fan 3 is located on the side of ventilation bag 2 away from seat foam 1, and is used to drive gas to flow through the first ventilation hole 11 and the second ventilation hole 21 on both sides of seat foam 1.

[0035] like Figure 1-3As shown, the first direction is the thickness direction of the backrest portion of the seat foam 1. The seat foam 1 has a first surface near the occupant and a second surface away from the occupant. Multiple first ventilation holes 11 are formed on the seat foam 1 and extend along the first direction to connect the first and second surfaces. The ventilation bag 2 is located on the side of the seat foam 1 away from the human body. The ventilation bag 2 includes two layers of TPU film, and the edges of the two layers of TPU film are sealed and welded. Multiple second ventilation holes 21 are formed on the first layer of TPU film near the seat foam 1, and a fan connection hole is formed on the second layer of TPU film away from the seat foam 1. At the same time, inorganic anti-adhesion agents and other materials can be applied to the second layer of TPU film for protection. The fan 3 is set at the fan connection hole and has an axial air inlet 31 and a circumferential air outlet 32. Its axial direction is... In the first direction, the ventilation bag 2 has an installation hole on the side away from the seat foam 1. The fan 3 is sealed to the installation hole so that the air inlet 31 of the fan 3 is connected to the inside of the ventilation bag 2, and its air outlet 32 ​​is located outside the ventilation bag 2. Under the drive of the fan 3, the gas can pass through the first ventilation hole 11, the air guide structure, the second ventilation hole 21 and the ventilation bag 2 in sequence, and then be drawn in through the air inlet 31 of the fan 3, and then discharged through the air outlet 32 ​​of the fan 3 to the side of the car seat away from the human body; or the air outlet 32 ​​of the fan 3 is connected to the inside of the ventilation bag 2, and its air inlet 31 is located outside the ventilation bag 2. Under the drive of the fan 3, the gas can be drawn in through the air inlet 31 of the fan 3, and then discharged through the air outlet 32 ​​of the fan 3 into the ventilation bag 2, and then pass through the second ventilation hole 21, the air guide structure and the first ventilation hole 11 in sequence, and then be discharged to the side of the car seat closer to the human body.

[0036] In traditional automotive seat ventilation systems, multiple first ventilation holes 11 are connected to second ventilation holes 21 via multiple independent interconnecting structures. When the distribution or position of the first ventilation holes 11 on the seat foam 1 changes, the ventilation bag 2 needs to be refitted. An air guide structure is located between the seat foam 1 and the ventilation bag 2. One end of the air guide structure can simultaneously connect to multiple first ventilation holes 11, and the other end can simultaneously connect to multiple second ventilation holes 21. Based on this, as long as the first ventilation holes 11 and the second ventilation holes 21 are distributed within the corresponding ranges at both ends of the air guide structure, multiple first ventilation holes 11 and multiple second ventilation holes 21 can be connected through the air guide structure, thus achieving the universality of the ventilation bag 2. By setting the air guide structure, it can simultaneously connect multiple first ventilation holes 11 on the seat foam 1 and multiple second ventilation holes 21 on the ventilation bag 2, avoiding the need to adapt different ventilation bags 2 for automotive seats with different structures, thus improving the applicability of the ventilation bag 2 and achieving the standardized universality of the ventilation bag 2.

[0037] In a preferred embodiment, the air guiding structure includes a connecting groove 12, which is opened on the side of the seat foam 1 away from the human body, and its bottom is connected to a plurality of first ventilation holes 11; a ventilation bag 2 is opened on the side of the seat foam 1 with a plurality of second ventilation holes 21, and the ventilation bag 2 covers the connecting groove 12.

[0038] like Figure 3 As shown, the connecting groove 12 is approximately a cuboid recess and is opened on the second surface of the seat foam 1. All the first ventilation holes 11 are connected to the bottom of the connecting groove 12. The ventilation bag 2 covers the opening of the connecting groove 12. The projection of all the second ventilation holes 21 along the first direction is located in the connecting groove 12. Thus, the multiple second ventilation holes 21 opened on the ventilation bag 2 can connect the connecting groove 12 and the interior of the ventilation bag 2, so that the gas can flow on both sides of the seat foam 1 through the first ventilation holes 11, the connecting groove 12, the second ventilation holes 21 and the ventilation bag 2 under the drive of the fan 3.

[0039] In a preferred embodiment, the connecting structure further includes a plurality of protrusions 13, which extend from the bottom of the connecting groove 12 toward the ventilation bag 2 and abut against the ventilation area. The plurality of protrusions 13 divide the internal space of the connecting groove 12 to form an air guide groove 14, which connects each of the first ventilation holes 11 and each of the second ventilation holes 21.

[0040] like Figure 3 As shown, in this embodiment, the protrusion 13 is approximately a triangular prism structure. In other embodiments of this application, the protrusion 13 may also adopt other structures such as a quadrangular prism or a cylinder, which are not specifically limited here. By setting the protrusion 13, the protrusion 13 extends from the bottom of the connecting groove 12 along the first direction toward the ventilation bag 2. Its free end abuts against the first layer of the ventilation bag 2 to support the ventilation bag 2. At the same time, multiple protrusions 13 separate the internal space of the connecting groove 12 to form an air guide groove 14. Multiple first ventilation holes 11 are connected to multiple second ventilation holes 21 through the air guide groove 14.

[0041] In a preferred embodiment, the projections of the plurality of first ventilation holes 11 and the plurality of second ventilation holes 21 along the first direction are all located within the air guide groove 14.

[0042] like Figure 3As shown, the projections of multiple first ventilation holes 11 and multiple second ventilation holes 21 along the first direction are all located within the air guide groove 14. That is, the first ventilation holes 11 and the second ventilation holes 21 are offset from the protrusion 13 in the first direction. Thus, the multiple first ventilation holes 11 can be connected to the second ventilation holes 21 through the air guide passage. When the gas flows from the first surface to the second surface of the seat foam 1 under the drive of the fan 3, the gas discharged through the first ventilation hole 11 can be introduced into the second ventilation hole 21 through the air guide groove 14. When the gas flows from the second surface to the first surface of the seat foam 1 under the drive of the fan 3, the gas discharged through the second ventilation hole 21 can be introduced into the first ventilation hole 11 through the air guide groove 14. By setting the multiple first ventilation holes 11 and multiple second ventilation holes 21 respectively to correspond to the air guide groove 14, the universal design of the ventilation bag 2 across all platforms can be achieved.

[0043] In a preferred embodiment, the ventilation bag 2 has a ventilation area and a connecting area on the side near the seat foam 1. All the second ventilation holes 21 are located in the ventilation area, and the ventilation area corresponds to the opening of the connecting groove 12. The connecting area is arranged around the ventilation area and is used to fix it to the seat foam 1.

[0044] like Figure 2 As shown, the first layer of TPU film on the side of the ventilation bag 2 near the seat foam 1 has a ventilation area and a connecting area. The ventilation area is located in the middle of the first layer of TPU film and its shape is approximately a rounded rectangle. Its shape and area are the same as the shape and area of ​​the groove 12. The area of ​​the first layer of TPU film near the seat foam 1, excluding the ventilation area, forms a connecting area. The connecting area can be connected to the seat foam 1 by gluing or welding, so that the ventilation bag 2 and the seat foam 1 are relatively fixed.

[0045] In a preferred embodiment, the seat foam 1 is further provided with a mounting groove 15, which is opened around the connecting groove 12. The mounting groove 15 is used to accommodate the ventilation bag 2, and the bottom of the mounting groove 15 is used to fix it to the connecting area.

[0046] like Figure 2 and Figure 3 As shown, the mounting groove 15 is also a rectangular recess. The mounting groove 15 is opened around the opening of the connecting groove 12. The shape and area of ​​the bottom surface of the mounting groove 15 are the same as the shape and area of ​​the connection area of ​​the ventilation bag 2. The mounting groove 15 is used to install the ventilation bag 2. The ventilation bag 2 is placed in the mounting groove 15. The connection area of ​​the ventilation bag 2 corresponds to and is fixed to the bottom surface of the mounting groove 15. The ventilation area of ​​the ventilation bag 2 corresponds to the opening of the connecting groove 12. Thus, while the ventilation bag 2 is fixed to the seat foam 1, the first ventilation hole 11 is connected to the second ventilation hole 21 through the connecting groove 12.

[0047] In a preferred embodiment, the plurality of protrusions 13 are arranged in an array.

[0048] like Figure 3 As shown, in this embodiment, each group of four protrusions 13 are distributed at equal intervals around the same center point, and multiple groups of protrusions 13 are evenly arranged in the connecting groove 12.

[0049] In a preferred embodiment, the ventilation bag 2 is provided with a pressure-bearing air guide 22, which is used to support the ventilation bag 2.

[0050] like Figure 4 As shown, the pressure-bearing air guide 22 can adopt the existing 3D spacer mesh fabric, which has several woven mesh holes and a certain thickness, with good air permeability and support. It can also ensure ventilation effect when squeezed by the human body. The pressure-bearing air guide 22 is filled inside the ventilation bag 2, and can be supported by the inside of the ventilation bag 2, so that the ventilation bag 2 is approximately a cuboid structure. The ventilation area and the connecting area are located on the end face of the cuboid structure of the ventilation bag 2 near the seat foam 1. At the same time, the porous structure of the 3D spacer mesh fabric can stabilize the gas pressure inside the ventilation bag 2 when the gas flows through the ventilation bag 2.

[0051] Example 2

[0052] This embodiment provides a car seat, including a car seat ventilation system with a universal ventilation bag as described in Embodiment 1.

[0053] The seat foam 1 is installed on the seat frame, and the seat foam 1 is covered with a seat cover made of breathable material. When the air inlet of the fan 3 is directly connected to the ventilation bag 2, the fan 3 is turned on. Driven by the fan 3, the gas can pass through the first ventilation hole 11, the air guide groove 14, the second ventilation hole 21 and the inside of the ventilation bag 2 in sequence from the side of the car seat closest to the human body, and then be drawn in through the air inlet 31 of the fan 3 and discharged through the air outlet 32 ​​of the fan 3. When the air outlet of the fan 3 is directly connected to the ventilation bag 2, the fan 3 is turned on. Driven by the fan 3, the gas can pass through the air inlet 31 of the fan 3 from the side of the car seat away from the human body, and then be discharged through the air outlet 32 ​​of the fan 3 into the ventilation bag 2. Then, it passes through the second ventilation hole 21, the air guide groove 14 and the first ventilation hole 11 in sequence and is discharged to the side of the car seat closest to the human body. Both of these methods can make the gas flow on the side of the car seat closest to the human body, so as to reduce the temperature on the side of the car seat closest to the human body and realize the ventilation function of the car seat.
